PATRICK GILLEN, OF LONDON, COUNTY OF MIDDLESEX, ENGLAND.

APPARATUS FOR THE GRADUAL REDUCTION OF GRAIN.

SPECIFICATION forming part of Letters Patent No. 307,386, dated October 28, 1884:.

Application filed May 27, 1884.

(No model.) Patented in England January 30, 1884, No. 2,400, and in Belgium June 12, I884,

To aZZ whom, it may concern Be it known that I, PATRICK GILLEN, a citizen of the United States, residing at London, in the county of Middlesex and Kingdom of England, have invented new and useful Improvements in Apparatusfor the Gradual Reduction of Grain, is a specification.

My invention relates to improvements in roller-niills and other mills for reducing grain in which the meal is passed from one pair of rolls or grinding apparatus through a reel or dresser to another pair of rolls, and so on from one series to another, the objects of my improvements being to combine several sets in a comparatively small space, and in such a manner that the parts shall be easy of access and of removal when'required. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a section through the two pairs of rolls and silk dresser; Fig. 2, an end view of same, partly in section. 'Fig. 3 is a vertical section of theelevator. Figs. 4, 6, and 8 are detail views of parts of said elevator, and Figs. 5, 7, and 9 respective sections thereof.

Similarletters refer to similar-parts throughout the several views.

A indicates one pair of rolls; B. a second pair. D is a cylinder or reel of silk, wiregauze, orother suitable screening material.

E is a circular elevator,which may be a ring or circle of any suitable material, having formed in or on its periphery recesses, cups, or concave compartments F, the open sides or faces of which revolve almost in contact with the periphery of the fixed disk or drum G, which keeps the contents of the cups F from escaping until required.

The construction of the elevator E is shown in detail in Figs. 3 to 9.

At Figs. 3, 4, and 7 it will be seen that the fixeddisk G has a recess or cavity, G, in which the meal collects, and also an opening or hopper, G", into which the meal is discharged from the cups F.

H is a hopper leading into rolls A; I, hopper leading from rolls A; K, a worm or creeper conveying meal into reel D; L, hopper leading from the opening G of the fixed disk G to the rolls 13.

of which the following venient source in a mill; but I may use any suitable driving-gear. The mill being atwork, the meal fed into H enters the rolls A, passes thence through I to the worm K, by which it is conveyed to the reel D, where it undergoes a first sifting and separation, the tine flour and lniddlings passing through the silk,and the remainder of the meal traveling to the opposite end of the reel, where it passes into the collector G of the fixed diskG, from whence it falls into the cups F of the elevator E, which carries it up and delivers it through the opening G" into the hopper L, from whence it passes into the second pair of rolls,B, and so on from one set of rolls and reels to another through out the mill.

I am aware that prior to my invention elevators have been placed at the end of sitting or separating reels operating in conjunction with roller mills. I therefore do not claim such a combination, broadly; but

What I do claim isl. The circular revolving elevator E, provided with cups F, opening directly toward the axis of said elevator, in combination with the fixed disk G, its rim covering the mouths of said cups, andv having openings at bottom and top, through which the material to be elevated passes respectively into and out of said cups. v

2. The two pairs of rollers A and B,in combination with an interposed inclined dresser, a circular elevator at its lower end,anda drivingshaft common to both.

3. The two pairs of rollers A and B, an interposed inclined dresser, and a circular elevator at its lower end upon its shaft of rotation. in combination with a-worm, K, for conveying the grain within the end ofsaid dresser.
